To all whom it may concern:

Be it known that l, Benno SEIDEL, a citizen of the United States, and resident oi Chicago, county of Cook, and State ci lllinois, have invented certain new7 and useful Improvements in Signal-Lanterns, of which the following is a speciiication, and which are illustrated in the accompanying drawings, 'forming a part thereof.

rlhe invention relates to that type or signal lantern in which there is provided a lighJf emitting lens and colored glasses mounted to be moved into and out oi register therewith.

The invention relates more specifically to the mechanism for controlling the Jframes carrying the color glasses; and it consists in the device hereinafter described and which is illustrated in the accompanying drawings, in which- Figure 1 is a detail sectional view of a lantern showing the signal glass-holders in elevation; Fig. 2 is a detail side elevation oil.2

the lantern showing-the casing for carrying the signal glass-holders; Fig. 3 is an inside view of the casing for carrying the signal glass-holders, and showing the glass-holders and operating mechanism in elevation; Fig. i is a sectional detail of the signal glass carrying mechanism. Fig. 5 is a detail elevation of the same.

The body of a lantern is represented at 10, and its light-emitting lens at 11. The casing 12 is attached to the exterior of the body ot' the lantern and open to its interior. i/Vithin this casing there is mounted the signal glass carrying mechanism. This mechanism con prises a pair of apertured frames 13, 1st, each carrying a glass plate 15, 16, secured in place by suitable mechanism. The frames 13, 14, are pivoted on a common axis, as shown at 17, within the casing 12, in such position that they may be swung into register with the lens 11 or raised above it. These frames are controlled by means of a short shaft 13, journaled in one of the walls ofthe casing 12, proa vided at its outer end with a suitable grip member, such as the knurled nut 19, and at its inner end with a plate 20, preferably squared as shown. The stems 21, 22, of the glass holders 13, 11i, are obliquely slotted back of the pivot 17, as shown at 27, 23, and within each of these slots there runs a stud 23, 24, iiXed, respectively, to links 25, 26, attached at diainetrically opposite corners oi the plate 20.

When both of the glass-carrying frames are out of service, in the position occupied by the frame 13 in Fig. 1, the studs 23, 24s, will be located at the upper ends of the slots 27, 23, respectively. The plate 2O will be so positioned that the pivots attaching the links 25, 26, thereto will be horizontally alined. rlhe Atrames 13, 14, are held in the out ot service position by any suitable means. As shown, springs 29, 30, are provided for this purpose, cach being coiled around the hub of one of the frames and reacting against the inner wall of the casing 12. The plate 2O is held against rotation by any suitable means. For this purpose 'there is shown a leaf spring 31, 'lined to the inner wall o'l the casing 12 and having at its free end a boss 32 bearing against the periphery of the plate and enter ing recesses 33, 3e and 35, at its corners. But one of the glass-carrying fr mes can be lowered at a time, and this is accomplished by turning the grip member 19 to the right or to the left through ninety degrees, the link cooperating with the holder to be lowered rising and drawing the bacl'wardly-projecting stein of the frame upwardly, thus rocking the frame on its pivot and bringing the glass into register with the lantern lens the pivot cooperating with the tramenot brought into service sliding to the lower end of its slot, as in the case oi the stud 23 in Fig. 1, thereby positively holding this frame out of service.

To prevent interference ot' the links with each other, one of them, as 25, is secured to the plate 2O by means of an outstanding bracket 36. The grip member 19 may be provided with a suitable indicator to show the position of the signal glass holders. There is shown for this purpose a linger 37, attached to the shaft 1S outside of the casing 12.

l claim as my invention- 1. in a lantern, in combination, a pair of glass-carrying frames pivoted at a common axis, an oscillating plate, and links connecting the frames and the plate each link having a lost motion engagement vnth one of the connected members.

2. in a lantern, in combination, a pair of oscillating glass-carrying frames pivoted on a common axis, and each having a slot in its stem, an oscillating actuating member, and links pivctally attached to such member each link having a stud ruiming in the slot ot' one of the frames.

3. In a lantern, in combination, a pair of oscillating glass-carrying frames each having a slot in its stem, an oscillating actuating member, and links connecting such member With each of the frames and' engaging the latter by studs running in the slots thereof.

4. In a lantern, in combination, a pair of oscillating glass-carrying frames each having a slot in its stem, an oscillating actuating member, links connecting such member With each of the frames and engaging the latter by studs running in the slots thereof, and springs for holding1 the frames in retracted position.

5. In av lantern, in combination, a pair of oscillating glass-carrying frames each having a slot in its stem, an oscillating actuating member, links connecting such member with each of the frames and engaging the latter by studs running in the slots thereof, and means for holding the frames in retracted position.

6. In a lantern, in combination, a pair of glass-carrying frames pivoted at a common axis, a notched oscillating plate, links connecting the framesV and the plate each link having a lost motion engagement with one of the connected members, and a detent for engaging the notches of the oscillating plate.'

7. In a lantern, in combination, a pair of glass-carrying frames pivoted on a common aXis, an oscillating plate, links connecting the frames and the plate each link having a lost motion engagement with one of the connected members, and means for turning the plate.

8. In a lantern, in combination, a pair of ing actuating plate, links attached to opposite corners of the plate and connected, respectively, with the frames.

9. In a lantern, in combination, a pair of oscillating glass-carrying frames, an oscillating actuating plate, links attached to opposite corners of the plate and each having a lost motion connection with one of the frames l0. In a lantern, in combination, a pair of oscillating glass-carrying frames each havingY a slot in its stem, an oscillating actuating plate, links attached to opposite corners of the plate each link having a stud engaging the slot in one of the stems.

11. In a lantern, in combination,a pair of oscillating glass-holding frames having a common axis, a single actuating shaft connected to both frames and arranged to adl Vance them alternatelywhen turned in opposite directions.

12. In a lantern, in combination, a pair of oscillating glass-holding frames having a common axis, a single actuating shaft connected to both frames and arranged to act on them in alternation by movement in opposite directions to advance one and lock the other.
